Advantages: The extra muzzle weight seems to add a little more balance to the gun and also reduces some of the muzzle jump. The calibration of the spring works well with both target and +P ammo. Spent brass travel four to six feet.
Disadvantages: Would have liked to have seen it come with a bushing like on after market 1911 kits. This would protect the slide from any kind of possible wear that may be caused by the spring/guide rod.
